Subject: [PATCH 19/39] mb/dell: Add Latitude E5530 (Ivy Bridge)

Mainboard is QXW10/LA-7902P (UMA). I do not physically have this board;
someone with physical access to one sent me the output of autoport which
I then modified to produce this port. I was also sent the VBT binary,
which was obtained from `/sys/kernel/debug/dri/0/i915_vbt` while running
version A21 of the vendor firmware.

This was originally tested and found to be working as a standalone board
port in Libreboot, but this variant based port in upstream coreboot has
not been tested.

This can be internally flashed by sending a command to the EC, which
causes the EC to pull the FDO pin low and the firmware to skip setting
up any chipset based write protections [1]. The EC is the SMSC MEC5055,
which seems to be compatible with the existing MEC5035 code.
